Question

What is the third side

Answer 1

A. 2.82 m

Explanation:

The missing side we are trying to find is the hypotenuse, this is because it is the longest side of a right triangle.

The Pythagorean Theorem is used:

`a^2+b^2=c^2`

Plug in the given numbers (2), accordingly:

`2^2+2^2=c^2\\4+4=c^2\\8 = c^2\\`

Take the square root of both sides:

`√(8) =√(c^2)`

2.82 ≈ c
